This paper introduces knowledgebase approximation and fusion using association rule aggregation as a means to facilitate accelerated insight induction from high-dimensional disparate knowledgebases. There are two typical observations that make approximating knowledgebases of interest: (1) It is quite often insights can be derived based partial set the samples, not necessarily all them; (2) gene...
کشف قوانین وابستگی (association rule) یکی از پرکاربردترین الگوهاییاست که توسط داده کاوی استخراج می گردند و به معنای یافتن همه قوانین موجود در مشاهده اقلام مجمو عه های داده ای است.مهمترین فاز یافتن قوانین وابستگی، یافتن الگوهای پرتکرار می باشد. کشف قوانین وابستگی در جریان سریع داده ها با مشکلاتی روبروست. با توجه به ماهیت جریان داده ای، امکان ذخیره سازی داده های ورودی و مرور دوباره آنها وجود ندا...
In recent years, the weakness of the canonical support-confidence framework for associations mining has been widely studied. One of the difficulties in applying association rules mining is the setting of support constraints. A high-support constraint avoids the combinatorial explosion in discovering frequent itemsets, but at the expense of missing interesting patterns of low support. Instead of...
The history of the GUHA method of automated generation of hypotheses is brieey sketched. Its main properties are listed. This serves to a comparison with present methods of mining association rules and hopes to inspire mutual innuence.
Texture can be defined as a local statistical pattern of texture primitives in observer’s domain of interest. Texture classification aims to assign texture labels to unknown textures, according to training samples and classification rules. Association rules have been used in various applications during the past decades. Association rules capture both structural and statistical information, and ...
This paper surveys some genetic-fuzzy data mining techniques for mining both membership functions and fuzzy association rules. The motivation from crisp mining to fuzzy mining will be first described. Three types of genetic-fuzzy data mining approaches are then described according to the utilized methods and different mining problems, including Integrated GeneticFuzzy approaches for items with ...
General fuzzy association rules mining focuses on finding out the fuzzy itemsets or fuzzy attributes which frequently occur together. But two fuzzy itemsets which frequently occur together can not imply that there is always an interesting relationship between them. In this paper, we develop an alternative framework for mining interesting relationship between fuzzy itemsets based on fuzzy correl...
